twtxt-lib

An isomorphic TypeScript library of utility functions for parsing and interacting with twtxt.txt files.

These functions include:

• hashTwt: takes the constituent parts of a “twt” and generates an extension-compatible hash for it.
• parseTwtxt: parses a twtxt file string, returning an object with information about the file and its owner (including hashes for each twt and any metadata in the file).
• loadAndParseTwtxtFile: fetches a twtxt file from the internet and parses it into an object (as above).

Features

• Isomorphic, available as an (optionally minified) ES6+ library for the browser, with NPM and JSR versions coming soon.
• Fully typed and source-mapped.
• Built as an ES6 module (and ESM only)
• Includes an interactive demo (you're looking at it).

Installation

This library can be installed in several different ways:

For the Browser

1. Grab the latest copy of the twtxt-lib.js file, either by downloading it from the git repo, the website, or doing a git clone https://git.itsericwoodward.com/eric/twtxt-lib.git and pulling it out of the dist-browser folder.
   • Alternatively, you can grab the minified version from the same sources.
2. Add the newly acquired file to your static site / progressive web app / over-engineered blog.
3. Import the desired function(s) via ESM: import { hashTwt, loadAndParseTwtxtFile } from "./twtxt-lib.js";

For Node

1. Add the package to your project.
   • Via NPM: yarn add twtxt-lib
   • Via JSR: yarn add jsr:@itsericwoodward/twtxt-lib
2. Import the desired function(s) into your code: import { hashTwt, loadAndParseTwtxtFile } from "twtxt-lib";
